What is the method for chestnuts to spread seeds?

Chestnuts spread seeds through the rolling and beating of fruits after natural drop, but today's chestnuts spread seeds artificially.

First, how to grow chestnuts?

1. Select a place

The sandy loam with low groundwater level and good drainage should be selected in chestnut orchard. Avoid saline-alkali soil, low humidity is easy to waterlogging, windy places to plant. In order to open up the millet garden in the hilly land, we should choose the areas near the mountains with gentle terrain and thick soil layer, and then gradually expand to the areas with poor conditions.

two。 Selection of species

The selection of varieties should be based on the excellent varieties selected locally, according to different edible requirements. For example, fried chestnut varieties and vegetable chestnut varieties should not only take into account the export of foreign trade, but also take into account the needs of the domestic market. At the same time to achieve a reasonable mix of early, middle and late varieties.

3. Planting

Reasonable close planting is the basic measure to increase the yield per unit area. It is suitable to have 30-40 plants per mu in plain chestnut orchard and 40-60 plants per mu in mountain chestnut orchard. It is planned that 60-111 trees can be planted in dense planting chestnut orchard per mu, and then thinning will be carried out step by step.

4. Fertilizer application

It is better to apply in autumn after fruit harvest, when the temperature is higher and the fertilizer is easy to mature; at the same time, it is in the period of new root occurrence, which is conducive to absorption, thus promoting the accumulation of tree nutrition and has a good effect on the differentiation of female flowers in the coming year. Topdressing is mainly based on available nitrogen fertilizer, combined with phosphorus and potassium fertilizer, the time of topdressing is in early spring and summer, 0.3-0.5 kg urea per tree in spring and 2 kg per tree in full fruit stage. After catching up, it should be combined with watering to give full play to the effect of fertilizer.

Summer topdressing is carried out from late July to mid-August. At this time, the application of available nitrogen and phosphorus fertilizer can promote the enlargement of the fruit grain, the fullness of the pulp and improve the fruit quality.

5. Pollination

Chestnut trees mainly rely on the wind to spread pollen, but because chestnut trees have heterogeneity of male and female flowers and self-fruiting, a single variety often produces empty buds due to poor pollination. So the newly built chestnut orchard must prepare 10% pollination trees. Practice has proved that it is better to use summer red as pollination tree in Xinyang City.

6. Watering

Chinese chestnut prefers water. Generally, irrigation once before germination and during the period of rapid fruit growth is beneficial to the normal growth and development of fruit trees and the improvement of fruit quality.
